Proximity-induced topological state in graphene
(Amer Physical Soc, College Pk, 2014)
The appearance of topologically protected states at the surface of an ordinary insulator is a rare occurrence and to date only a handful of materials are known for having this property. An intriguing question concerns the ...
Improving reactivity of fly ash and properties of ensuing geopolymers through mechanical activation
(Elsevier Sci Ltd, Oxford, 2014)
This paper investigated the effects of mechanical activation of fly ash (FA) from thermal power plants on physical-mechanical properties and structure of geopolymers. FA from different power plants in Serbia was mechanically ...
Contrasting effect of silicon on iron, zinc and manganese status and accumulation of metal-mobilizing compounds in micronutrient-deficient cucumber
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2014)
Although the beneficial role of silicon (Si) in alleviation of abiotic stress is well established, little is known of the relevance of Si nutrition under microelement deficiency. The aim of our work was to investigate the ...
Raman Responses in Mechanically Activated BaTiO3
(Wiley, Hoboken, 2014)
The structure and lattice dynamics of mechanically activated BaTiO3 was investigated in this study. Phonon behavior and crystal structure stability of the obtained nanocrystalline BaTiO3 were discussed from the view point ...
Morphological and crystallographic characteristics of lead powder obtained by electrodeposition from an environmentally friendly electrolyte
(Elsevier Science Bv, Amsterdam, 2014)
Lead powder obtained by potentiostatic electrodeposition from alkaline electrolyte, based on hydroxide ions, was investigated. The shape of lead crystals strongly depends on overpotentials of electrodeposition. The regular ...
Assembly Processes under Severe Abiotic Filtering: Adaptation Mechanisms of Weed Vegetation to the Gradient of Soil Constraints
(Public Library Science, San Francisco, 2014)
Questions: Effects of soil on vegetation patterns are commonly obscured by other environmental factors; clear and general relationships are difficult to find. How would community assembly processes be affected by a substantial ...
Novel simple methods for the synthesis of single-phase valentinite Sb2O3
(Springer, Dordrecht, 2014)
Several methods with solid and dissolved reactants were investigated as possible routes for synthesis of single-phase valentinite Sb2O3. The methods are based on simple chemical reaction between SbCl3 and NaOH. The method ...
Differential response of antioxidative systems of maize (Zea mays L.) roots cell walls to osmotic and heavy metal stress
(Wiley, Hoboken, 2014)
An analysis of peroxidase and ascorbate oxidase activity, phenolic content and antioxidant capacity of isolated maize root cell walls was performed in controls and plants stressed with polyethylene glycol (PEG) or heavy ...
Filter strip as a method of choice for apoplastic fluid extraction from maize roots
(Elsevier Ireland Ltd, Clare, 2014)
Apoplastic fluid was extracted from maize (Zea mays L) roots using two procedures: collection from the surface of intact plant roots by filter paper strips (AF) or vacuum infiltration and/or centrifugation from excised ...
Metals and electrolytes in sclerotic hippocampi in patients with drug-resistant mesial temporal lobe epilepsy
(Wiley-Blackwell, Hoboken, 2014)
An altered metal and electrolyte profile has been implicated in the pathologic mechanisms of chronic epilepsy; however, no study has comprehensively measured hippocampal concentrations of these elements in patients with ...
